Abstract – The concept Door locking and unlocking systemuses GPRS to open and close the door. In addition to this thesecurity will be provided using GSM in case of anyunauthorized access. The main aim of this project is toprovide security at homes, offices etc. The systemautomatically locks the door as soon as it receives predefinedmessage from the user. The user will have to first register.His information will be stored in database. Whenever themessage will be received for the registered number, thecontroller will accordingly give instruction to DC motor. DCmotor will then perform action on door either locking orunlocking. In case of unauthorized access, the IR sensor willsense the action and send the alert message to the registereduser using GSM.

Keywords – Global System for Mobile Communication(GSM), General Packet Radio Service (GPRS),Microcontroller, DC Motor, IR Sensor.

I. INTRODUCTION

The system automatically locks and unlocks the door assoon as it receives a predefined message from the user.The system provide security at homes, offices etc. Thereare many systems which has been developed till nowwhich were working on the technologies such as enteringpasswords, wireless networks etc. but the disadvantagesshown by them were not so secure also it required physicalpresence. Here we are developing a system which is moresecure and cost efficient.

II. PROPOSED SYSTEM

The project intends to interface the microcontroller withthe GSM modem and start/stop the vehicle engine bysending the predefined messages from the mobile to thecontrolling unit. The project uses the GSM technology andEmbedded Systems to design this application. The mainobjective of this project is to design a system thatcontinuously checks the messages if any, received fromthe user mobile and change the status of the engine as perthe message received from the mobile

The main concept behind the project is receiving thesent SMS and processing it further as required to performseveral operations. The type of the operation to beperformed depends on the nature of the SMS sent. Theprinciple in which the project is based is fairly simple.First, the sent SMS is stored and polled from the receivermobile station and then the required control signal is

generated and sent to the intermediate hardware that wehave designed according to the command received in formof the sent message. The messages are sent from themobile set that contain commands in written form whichare then processed accordingly to perform the requiredtask.

III. TERMINOLOGY

A. Global system for mobile communication (GSM)GSM was developed with a moderate level of service

security the GSM system is designed to authenticate theuser with the previously shared key and the challengeresponse. Communications between the sender of systemand the base station can be encrypted. The security modelis therefore used to provide confidentiality andauthentication but it has limited authorization and it isnon-repudiation.B. General packet radio service (GPRS)

General packet radio service is used as a packet orientedmobile data service. It is used in 2G and 3g cellular mobilecommunication system for GSM mobiles which is chargedas per minute connection. GPRS provides the data rate of56-114 Kbit/second. GPRS system enables the SMSmessaging and broadcasting of messages. It supports themultimedia messaging service. It is better suites theinternet application for smart devices through WAP. Itsupports the services like point-to point, point-to-multipoint, multicast, and point-to-multicast.

C. ARM-7 microcontrollerArm7 is a versatile processor that is designed for the

mobile devices and other low power electronics. thisprocessor is capable of up to 130 MIPS on the typical 0.13μm process. The specialty of 128 bit wideinterface/accelerator enables with the high speed. It is alow power consumption device. It supports the powersaving mode and includes the idle and power down option.D. IR sensors

Infrared radiation is the part of electromagneticspectrum having wavelengths longer than visible lightwavelengths, but usually smaller than microwaves, i.e., theregion roughly lies from 0.75μm to 1000 μm is theinfrared region. Infrared waves are not visible to humaneyes.

IV. WORKING

The system is based on sending and receiving the SMSfrom the control unit and the mobile user. The sender whois operating the system can lock or unlock the door usingthe SMS system which is based on the GPRS and GSMservice. The user will login into the system and get thelogin ID and the password which will make him theauthenticated user. This username and password will beused for the door operations. Also all the informationregarding the users will also is present in themicroprocessor.

As soon as the user will send the SMS for lockingcontroller will check the present status and inform theuser. The controller will pass the signals to the motor thatis present on our door to close the door. Also the reverseprocess will take place on the unlocking time.

By mean time if there is any theft on our door the IRsensor will detect the intensity breakout that is not basedon signal, as our IR sensor are getting the signals fromcontroller. It will pass the message of warning or theft ondoor. The controller will send the alert to the GSM moduleand then message will be passed to the user of the system.This way we can receive the alerts of the door actions. Theoperating door which is forcefully opened will again bereset to the original position of the user (in case of open orclose). The Circuit results are displayed in followingmanner. The LED displays the exact action of door.

Fig.3. Thefts warning when door has been forcefully open

The GPRS system will also be able to track theoperation of the door by giving the door status. We arealso using GSM service to receive the message of the dooroperation if there is any theft on the door. IF anyunauthorized person tries to attack on door or forcefullyopens the door, then the user receive message regardingthe theft.

Fig.4. Circuit of Door operation through GSM/GPRStechnology

The circuit consists of the UART microcontroller whichis controlling door operation .The microcontroller ismounted with the LED display which is showing the statusof the Door. There is a GSM module that is used to givethe details of the door operation to the user when user isoperating. The IR sensor will be adjusted in such a waythat there will be a quick alert if the door is openedforcefully .The intensity of light will detect the theft ondoor. The theft message will be sensed by the controllerand sent to the GSM module, from the GSM module theuser will receive the message. There is a DC motor who iscontrolling the opening and closing operation, when theuser sends the message it acts accordingly.

VI. APPLICATION AND ADVANTAGES

Cost Effective Can be used in various rooms like seminar hall,

conference room, and study rooms in college where thecapacity of room is limited and should not be exceeded.So the project will display the actual number of personsinside the room.

FUTURE DEVELOPMENT

We can monitor and control more parameters anddevices.

Voice announcement system can be added to indicatedevice conditions.

We can implement other related modules like firesensor, wind sensor.
